Wilson Python 98 — First Look at Wilson's New Pro Stock Frame (2025)

Confirmed specs

The following specifications come from Holy Tennis, one of the few retailers currently selling prototype units:

Spec	Wilson Python 98
Head size	98 sq in
Weight (unstrung)	302g
Balance	315mm from butt
RA Stiffness	65
String pattern	16x20
Length	27 inches (standard)

These are prototype measurements — production specs may vary slightly when the frame officially launches.

What the 16x20 pattern means

The most distinctive aspect of the Python is its 16x20 string pattern. This sits between the standard 16x19 (open, used by most spin-oriented frames) and the 18x20 (dense, used by control frames like the TF40 and Blade 18x20). Having 16 mains with 20 crosses is unusual — it gives you the wide vertical spacing of a 16-main pattern for lateral string movement, while the additional cross strings add more durability and a slightly crisper response than a pure 16x19.

In practice, expect spin potential slightly below a 16x19 but meaningfully better than 18x20. Think of it as a control-biased open pattern — the kind of setup that appeals to players who want both access to spin and consistent string response.

How RA 65 positions it

At RA 65, the Python is in the flexible-to-medium range. For context: the Wilson Blade 98 v10 is RA 62 (very flexible), the HEAD Speed MP is RA 67 (medium), and the Babolat Pure Aero is RA 69 (stiff). RA 65 means the Python will have a distinctly softer feel than most power frames while offering more feedback and arm-friendliness than average. Players with arm sensitivities should find it comfortable.

Python vs Wilson Blade 98 16x19 v10

	Python 98	Blade 98 16x19 v10
Weight	302g	304g
RA stiffness	65	62
String pattern	16x20	16x19
Balance	315mm	~320mm

The Python is 2 points stiffer than the Blade — enough to feel more positive and lively on impact, but still firmly in the comfortable range. It's lighter at 302g and uses more crosses (20 vs 19), which will give it a slightly crisper string bed response. Players who find the Blade 98 too soft or lacking feedback might find the Python strikes a better balance.

Python vs Babolat Pure Aero 2026

	Python 98	Pure Aero 2026
Weight	302g	300g
RA stiffness	65	69
String pattern	16x20	16x19
Character	Control + spin	Spin + power

The Pure Aero and Python have similar weights, but 4 RA points separate them significantly. The Aero's stiffness generates more natural power and is built around maximising spin. The Python sacrifices a little spin potential for notably more control and comfort — a better choice for players who want to dial in precise shots rather than hit heavy topspin.

Who is the Python for?

Based on the specs, the Python 98 looks designed for an advanced all-court player who wants more feedback and control than the Pure Aero provides, but prefers the liveliness of RA 65 over the very flexible Blade 98. The 16x20 pattern signals a player who values both string durability and consistent response over maximum spin.

At 302g, it's not the heaviest frame, so it may also appeal to players making the transition from lighter rackets who want to move toward a more control-oriented setup without going to a heavy 315–320g frame.

Availability

The Python is currently only available as a prototype/pro-stock unit from specialist retailers like Holy Tennis. No official retail launch date has been confirmed by Wilson. Given that it's available in a snakeskin prototype paint job, it's likely being tested by touring professionals before any official announcement.
